You don't need this running unless your wireless devices don't work without it. So, turn it off, as it seems to send and recieve and take up bandwidth.....and you don't even know what it's sending and receiving! Isn't it funny that Microsoft doesn't tell you.

It's the wireless config driver. It's not necessary, but helps some wireless cards work better.

ndisuio.sys will duplicate itself when deleted from the system file driver cache, it will also not disable when wireless services are disabled under admin tools/services. Sygate is constantly blocking it, which is a good thing, leading me to believe it is not at all essential for xp functionality at my level of pc use. Side note sygate was bought out by symantec (sic) coporate conspiracy theory abounds. This little humdinger is nothing but trouble. Why would a system routine be impervious to user disabling? I have yet to experiment with wireless apps, I dont do wireless.
